a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
BACKGROUND Cardiac resynchronization therapy defibrillator (CRT-D) devices are now capable of monitoring changes in intrathoracic impedance. Intrathoracic impedance monitoring resulting in a fluid index threshold crossing has been proven to predict heart failure (HF) exacerbations. We retrospectively investigated the relationship between changes in intrathoracic impedance and the occurrence of ...
BACKGROUND Cardiac resynchronization therapy (CRT) improves functional capacity in heart failure patients. This study aimed to prospectively analyze long-term device-based monitoring of physical activity in patients undergoing CRT. METHODS AND RESULTS The Activity Log Index (ALI), calculated by CRT devices, represents the percentage of time when acceleration exceeds a threshold and monitors t...
BACKGROUND Cardiac resynchronization therapy (CRT) is a relatively new treatment strategy for patients with heart failure and mechanical asynchrony. Reported effects of CRT on regional myocardial blood flow (MBF) are conflicting, and effects on hyperemic MBF are scarce. The aim of the present study was to assess serial changes of MBF and MBF reserve in patients receiving a biventricular pacemak...
PURPOSE The purpose of this study was to compare the survival of patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) undergoing concurrent chemoradiotherapy (CRT) alone with that of patients undergoing induction chemotherapy (IC) using docetaxel, cisplatin, and 5-fluorouracil (TPF) followed by CRT. MATERIALS AND METHODS A search of the PubMed, EMBASE, and Cochrane ...
cognitive rehabilitation therapy is an effective therapeutic program to restore functioning and compensate cognitive deficits of numbers of involved traumatic brain injury individuals as well as many psychiatric patients, of them ptsd in particular. specific skills and metacognitive strategies help patients to create self-awareness and learn how to monitor these skills. metacognitive training i...
Background: Breast cancer is the most common type of cancer in women demanding accurate diagnosis to take remedial measures to treat.Objective: Comparing the diagnostic capability of the computer regulation thermography (CRT), as a novel and safe diagnostic procedure, with common methods including sonography, mammography and clinical examinations for diagnosing breast cancer in suspicious...
BACKGROUND Cardiac resynchronization therapy (CRT) is effective in reducing clinical events in patients with heart failure and prolonged QRS interval. Studies using surrogate measures and subgroup analysis of large trials suggest that only patients with severely prolonged QRS benefit from CRT. Our objective was to determine whether the effect of CRT on adverse clinical events (eg, death, hospit...
two continuously regenerating traps crt-a and crt-b were evaluated under the controlled carbonyl emissions from a turbocharged diesel engine run on an ac electrical dynamometer. the gas-phase carbonyls were taken in silica gel cartridges coated with 2,4-dinitrophenylhydrazine both upstream (baseline) and downstream of the traps, and a total of fourteen carbonyls were identified and then quantif...
Secure communication has become more and more important for system security. Since avoiding the use of encryption one by one can introduce less computation complexity, secret sharing scheme (SSS) has been used to design many security protocols. In SSSs, several authors have studied multipartite access structures, in which the set of participants is divided into several parts and all participant...
